Use the Test-SmtpConnectivity cmdlet to diagnose whether
an SMTP connection can successfully be established to the Receive
connectors on a specific server. Although you can run this cmdlet
manually to verify SMTP connectivity for a specified server, it's
primarily used by Microsoft System Center Operations Manager 2007
to test your transport servers' ability to receive SMTP connections
to each of the bindings on all the Receive connectors on those
servers.

Syntax

Detailed
Description

When you run the Test-SmtpConnectivity cmdlet
against a Hub Transport server, the cmdlet attempts to establish an
SMTP connection to all bindings of all Receive connectors hosted on
that server. For each attempt, the cmdlet returns the following
information:

Server The name of the server that
hosts the Receive connector.

ReceiveConnector The name of the
Receive connector to which the SMTP connection was attempted.

Binding The binding that was configured
on the Receive connector.

EndPoint The actual IP address and port
to which the SMTP connection was attempted.

StatusCode The result of the connection
attempt. This can be one of the following: Success, Unable to
connect, Transient error, Permanent error, External error.

Details The actual response received
from the server being tested. If the connection attempt isn't
successful, this field contains an error string.

You need to be assigned permissions before you can run
this cmdlet. Although all parameters for this cmdlet are listed in
this topic, you may not have access to some parameters if they're
not included in the permissions assigned to you. To see what
permissions you need, see the "Testing mail flow" entry in the
Transport
Permissions topic.

Parameters

Parameter

Required

Type

Description

Confirm

Optional

System.Management.Automation.SwitchParameter

The Confirm switch causes the command to pause processing
and requires you to acknowledge what the command will do before
processing continues. You don't have to specify a value with the
Confirm switch.

DomainController

Optional

Microsoft.Exchange.Data.Fqdn

The DomainController parameter specifies the fully
qualified domain name (FQDN) of the domain controller that
retrieves data from Active Directory. The DomainController
parameter isn't supported on the Edge Transport server role. The
Edge Transport server role reads only from the Active Directory
Lightweight Directory Services (AD LDS) instance.

Identity

Optional

Microsoft.Exchange.Configuration.Tasks.ServerIdParameter

The Identity parameter specifies the transport server for
which the cmdlet verifies SMTP connectivity. The cmdlet verifies
SMTP connectivity for all Receive connectors hosted on the
specified server. If no server is specified, the cmdlet attempts to
perform the SMTP connectivity test against all Receive connectors
on the local server. If the local server isn't a Hub Transport or
Edge Transport server, the cmdlet returns the error: "Server
<servername> is not a Transport server".

MonitoringContext

Optional

System.Boolean

The MonitoringContext parameter specifies whether the
results of the test are written to the monitoring event log using
the monitoring infrastructure. If you set this parameter to
$true, the cmdlet generates events for the monitoring
infrastructure. If you set this parameter to $false,
the cmdlet only displays the results in the Exchange Management
Shell.

The default value is $false.

WhatIf

Optional

System.Management.Automation.SwitchParameter

The WhatIf switch instructs the command to simulate the
actions that it would take on the object. By using the
WhatIf switch, you can view what changes would occur without
having to apply any of those changes. You don't have to specify a
value with the WhatIf switch.

Input Types

Type field for a cmdlet is blank, the cmdlet doesn’t accept input
data.

Return Types

To see the return types, which are also known as output
types, that this cmdlet accepts, see Cmdlet Input and Output Types. If the Output Type
field is blank, the cmdlet doesn’t return data.
